Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains Netfilter fixes for you net tree, they are: 1) Restore __GFP_NORETRY in xt_table allocations to mitigate effects of large memory allocation requests, from Michal Hocko. 2) Release IPv6 fragment queue in case of error in fragmentation header, this is a follow up to amend patch 83f1999caeb1, from Subash Abhinov Kasiviswanathan. 3) Flowtable infrastructure depends on NETFILTER_INGRESS as it registers a hook for each flowtable, reported by John Crispin. 4) Missing initialization of info->priv in xt_cgroup version 1, from Cong Wang. 5) Give a chance to garbage collector to run after scheduling flowtable cleanup. 6) Releasing flowtable content on nft_flow_offload module removal is not required at all, there is not dependencies between this module and flowtables, remove it. 7) Fix missing xt_rateest_mutex grabbing for hash insertions, also from Cong Wang. 8) Move nf_flow_table_cleanup() routine to flowtable core, this patch is a dependency for the next patch in this list. 9) Flowtable resources are not properly released on removal from the control plane. Fix this resource leak by scheduling removal of all entries and explicit call to the garbage collector. 10) nf_ct_nat_offset() declaration is dead code, this function prototype is not used anywhere, remove it. From Taehee Yoo. 11) Fix another flowtable resource leak on entry insertion failures, this patch also fixes a possible use-after-free. Patch from Felix Fietkau. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
